There is a corresponding announcement on the same day (25/06/18) from APA bit I don't seem to be able to paste the link but it's easy enough to find.
Extract...
"Managing Director Mick McCormack said, “IPL is a foundation customer of APA and it is very pleasing to help an industrial customer, particularly one with an almost 100 year history of manufacturing in Australia.
“APA is pleased to have been able to help make this deal happen, not only through our investment in developing the East Coast Grid over many years, but also because we have worked very closely with IPL to understand and then meet their needs by providing services in a market which is currently in tight supply.”
